How to identify unknown frequencies and durations dynamically through LabVIEW from a signal which has many frequencies?

Thanks Bob and Henrik !!!

Johnsold,

It is working Great, Thanks a lot!!!

I am able to segregate frequencies its stat time and end time. Yes, the description about the frequencies are expected and not the actual. Some clarifications below

Scenario1:- there is one frequency for long duration (till we stop that frequency) and it is detected as different blocks of different durations. Can we define any threshold to detect that as single frequency of one duration (See Signal1 of the attached vi)

Scenarios2:-  Two frequencies will occur on same point of time and in that case only one frequency is detected. Is it possible to modify this logic to make both frequency detected? (See Signal1 +Signal2 of the attached vi)
